You can probably find 3x used HD 7950's for $150~$140 each on craigslist. 5-6 BTC is about $600 to $800 worth, it's possible under that budget. At worst, you might have to run 2x HD 7950's if you can't get it within that budget range.
Yea I am seeing the 7950's going for $165 on ebay. The problem for me is that I live in the middle of nowhere (3 hours north of SF) so craigslist is kinda out of the question for me unless some one will ship to me . I would really like to spend only BTC on this project, seems that everything on bitmit.com is so over priced. Ill keep scouring the marketplace here for a bit until I get annoyed. When it comes to paying with BTC, people under value it. You might be best to convert it to cash at Coinbase. They are located in the US and pretty trustworthy. People are dumping they HD 7950's and 7970's for the new AMD R9 290/290X. Good time to start picking up these cards on the cheap. I saw some sold a 7950 for $120 in Oakland. I live in the San Joaquin Valley, about 1hr 20 min to 1hr 35 min for SF. Converting the coin is just what Im trying to avoid. I dont like the idea of having to convert the currency to have to use it. I saw this card http://sfbay.craigslist.org/sby/sys/4063774905.html today but once again Im not really willing to drive all the way down after gas and my time Im way over paying. Thanks for all your input bud I do appreciate you. I have a few offers pending on our marketplace Ill go from there. I think that finding the cpu/mb combo is going to be a chore I may just get that on ebay. I just found this motherboard http://www.amazon.com/Gigabyte-Intel-CrossFireX-Motherboard-GA-P75-D3/dp/B007R9CRJE/ref=sr_1_4?s=electronics&ie=UTF8&qid=1350950330&sr=1-4&keywords=gigabyte+lga+1155+b75?ie=UTF8&tag=tonymacx86com-20

Hm.., you might want to consider cex.io (referral link), it let you buy GH/S and collect dividend daily. Free electricity, management fee and etc. Boring. I want to build this rig that is the appeal to me.

3BTC shipped for 3 7950's

i got lazy and stopped selling my stuff a couple months ago (at least I sold all my 5970's, hoho)
anyway, I have:
2 or 3x 5830's without fans 2 or 3x 5870's without fans
(a friend that pays 0 electricity was mining with these for a while and I haven't even opened up the box when he returned them, but I know the fans dont work.. ^^ those are the card only, nothing else)
and then,
2x Sapphire 6990's 1x MSI 7770 1x Powercolor 7790 1x MSI 7790 1x MSI 7850 1x XFX 7850 1x Powercolor 7950
the MSI's all have warranties that are based off manufacture date, so they'd all transfer over. they all have about 2 1/2 years left. pretty sure all the rest can't be transferred
for ^^ that stuff, I have all the original materials (box, manual, cd, sticker, whatever else) except for the two 6990's
asking price is negotiable, but, no, i'm not going to take some ludicrous offer (like $275 for five 5970s on some other thread). look at ebay completed auctions for the last month, look at what they sold for (remember to add shipping charge), and I'd be looking for something like that value minus 35% (obviously the 5830s and 5870s would be much less, since they'd have to be listed as 'damaged' w/o the fans)
What will you take for the 2x Sapphire 6990's and the Powercolor 7950?

One the low low budget, you can get away with HD 5850, 5870, 6950 and 6970. Next would be HD 5970 and 6990. Then the best power/hash rate would go to the HD 7950. Best to stay with the 7900's series at least for best performance. You can get away with 4 GB system ram and a decent single or dual core cpu. Best to have an open setup, then a case for cooling. Also have a good 750 watt PSU at least, but I would suggest 1000 watt to 1200 watt, depending if your going run more then 3x HD 7950's.
So it seems that I could build a rig that runs 3x HD 7950's for the budget Im setting for myself. What kind of Mh/s would I be looking at? Any suggestions on a MB or MB CPU combo? Also where should I begin looking to purchase some of this gear with btc other than the here?

9rbygb79BUvPt9oP6y6tskB1Pf8xxdyFMs Thanks bud! What pool are you mining in I would like to point my hashing power that direction for a while. (edit: Just noticed that coinex is a pool. thanks for the link)

Most SHA-256 coins can be.. Check out coinchoose.com for a list
Thanks for your reply. It looks like Terracoin is the way to go if i give up on BTC. I have been mining TRC for the last 24 hours and I probably will keep going till I hit 100 coins (about 3 days) its been an interesting experiment so far.

I would like to build a LTC and have about 5-6btc to invest. Could you guys help me get a rig up and running for that budget? Is this just the worst idea ever? I think it will be a fun project to build and at least the gpu's can be resold a a reasonable price if I decide to give it up.

I cannot get a hash rate per minute to display using my block erupters. What difficulty should I be set at I have tried several with no change. I am hashing at 12+gh/s [edit new content]
I am also getting aroud 50% hardware errors while mining in this pool. I dont see anything over 1% anywhere else.

Told seller I would be interested in a single unit shipped to Canada. Seller immediately asked for 70% upfront and 30% on delivery. I said I'm only interested if escrow is involved with either someone here on the forums or btcrow, seller declined escrow for the reason that he wants to order a 600gh/s card from BFL and does not want to wait for escrow. He then switched it to 50% upfront and 50% on arrival. SCAM WARNING
